The following paragraph is very insightful…and a cause for concern:
“[The surveillance industry] is, in practice, unregulated. Intelligence agencies, military forces, and police authorities are able to silently, and on mass, and [sic] secretly intercept calls and take over computers without the help or knowledge of the telecommunication providers,” wrote Wikileaks in its report. “In the last ten years systems for indiscriminate, mass surveillance have become the norm.”
The above comes from an ArsTechnica article entitled, “Wikileaks docs reveal that governments use malware for surveillance“.
